Sodium Octyl Sulfate is an anionic surfactant also known as sodium n-octyl sulfate with the chemical formula C₈H₁₇NaO₄S. Its structure contains an eight-carbon hydrophobic chain connected to a hydrophilic sulfate group giving it characteristic surface-active and ion-pairing properties. In biochemical research, the compound is valuable for investigating protein-surfactant interactions, including albumin enrichment and changes in protein structure or enzyme activity. It is also studied in mixed surfactant systems to understand interactions between anionic and cationic surface-active compounds.

Sodium octyl sulfate is used as an anionic surfactant, detergent and ion-pairing reagent. In research laboratories, it is particularly useful in HPLC, albumin enrichment studies, surfactant interaction research and investigations involving proteins and biological membranes.
Sodium Octyl Sulfate is an anionic surfactant, also known as Octyl Sulfate Sodium Salt or Sodium Capryl Sulfate, widely used as a detergent, wetting agent, and laboratory reagent.
Sodium Octyl Sulfate and Sodium lauryl sulfate are not the same compound. They are distinct anionic surfactants with different carbon chain lengths and chemical formulas. Sodium octyl sulfate has an eight-carbon chain, while sodium lauryl sulfate has a twelve-carbon chain.
Sodium Octyl Sulfate is used as an ion-pairing reagent in HPLC, where it interacts with positively charged analytes to form ion pairs, increasing their retention on reversed-phase columns and improving chromatographic separation.
